Beware. While the other replies are correct that the FB apps allows you to choose the level of syncing, it doesn't work properly with the Droid X (at least on 2.1)

It doesn't work in 2.2 (Droid 2), either. It adds a second "Facebook" icon to the account setup menu (the first is Motorola's version that adds them all without any choice), but it doesn't do anything.
